Recently, I was speccing my PC interface for an X-10 controller, and
decided on the TW7223, as it was the cheapest available. I had to write
a driver for it, as there wasn't anything useful available.
The TW7223 cost me £26. If I'd wanted a serial convertor so I could
talk to it from my PC's serial port, it would have set me back an
astonishing £64.63, and that's on top of the £26 for the TW7223.
The other popular option appears to be the CM12U, which again is a
serial port interface, and costs £64.63 also. Granted, it has some
extra features like battery backup, PC-less operation, etc.
It seems to me that the non-X10 parts of these adaptors are far too
expensive. Given a TW7223 OEM X-10 controller, I reckon a small
board could be knocked up to provide all the relevant functionality
for about a tenner.
Frankly, I'm tempted to do it. I assume that given the amount of
HA software that speaks CM12U, the interface to it is publically
available?
cheers
